Methods: Taking advantage of the special mechanics action of nitinol shape memory alloy, and taking into account of the anatomic mechanics characters of proximal humerus, a nitinol connector named proximal humerus memory connector (PHMC) was designed.

• 方法:利用镍钛合金与肱骨近端解剖生理的特性和特征,研制肱骨近端记忆接骨器(Proximal humerus memory con- nector PHMC)。
